Description
- Demonstrate soil characteristics with easy-to-perform activities
- Sample runoff water to quantitatively evaluate erosion control
- Relate soil properties to sustainable agricultural practices
Students explore the formation of soil and its physical properties when it reacts with water. Performing 3 different activities over 2 lab periods, students investigate weathering of rocks, particle size composition of local soils, and the rate of permeability of different soil samples. They then apply their knowledge to construct a model of a slope that has been cleared for farming and design a plan that modifies the slope to reduce erosion.
